"
   * 11 March 2011: the Japanese government declared a nuclear power emergency due to the failure of the reactor cooling systems in one of the reactors of Fukushima I and evacuated thousands of residents living close to the reactor. After officials later voiced the possibility of core damage, the evacuation zone was extended to 20 km, affecting 170,000–200,000 people,[8][9] and residents within a further 10 km have been advised to stay indoors. Twenty-two residents near the plant showed signs of radioactive contamination exposure, and three workers from the plant reported symptoms of radiation sickness,[10] but only one worker was confirmed to be ill by the Tokyo Electric Power Company (TEPCO).[11] The release of fission products from the damaged nuclear reactor core, notably radioactive iodine-131, led Japanese officials to distribute prophylactic iodine to the people living around Daiichi and Daini.[10]

   * 12 March: while evidence of partial meltdown of the fuel rods in Unit 1 was growing, a hydrogen explosion destroyed the upper cladding of the building housing Reactor Unit 1. The explosion injured four workers, but the reactor containment inside the building remained intact.[12][13] The explosion is believed to be the result of a buildup of hydrogen within the building after it was vented along with steam to reduce pressure within the containment vessel.[14][15] Hydrogen is formed when overheated zircaloy reactor fuel rods oxidize with water.[16] Operators of the plant were authorised to commence using sea water for emergency cooling, which will permanently damage the reactor beyond further use.

   * 13 March: a partial meltdown also appeared possible at Unit 3. As of 13:00 JST, both reactors 1 and 3 were being vented and re-filled with water and boric acid to reduce temperatures and inhibit further nuclear reactions.[17] Unit 2 was reported to have lower than normal water level but to be stable, although pressure inside the containment vessel was high.[17] The Japan Atomic Energy Agency announced that it was rating the situation at Units 1 and 3 as Level 4 (accident with local consequences) on the International Nuclear Event Scale (INES).[18]

   * 14 March: the reactor building for Unit 3 exploded[19] injuring eleven people. There was no release of radioactive material beyond that already being vented but blast damage affected water supply to Unit 2.[20] The president of the French nuclear safety authority, Autorité de sûreté nucléaire (ASN), said that the accident should be rated as a 5 or even a 6 on INES.[21]

   * 15 March: problems with the vents on Unit 2 apparently meant that pressure in its containment vessel had prevented adding water, to the extent that Unit 2 was in the most severe condition of the three reactors.[22] An explosion in the "pressure suppression room" caused some damage to Unit 2’s containment system.[22][23] A fire broke out at Unit 4 involving spent fuel rods from the reactor, which are normally kept in the water-filled spent fuel pool to prevent overheating. Radiation levels at the plant rose significantly but have since fallen back.[24] A radiation equivalent dose rate was observed at one location in the vicinity of Unit 3 of 400 millisievert per hour (400 mSv/h).[25][26][27]

   * 16 March: at 5:45 a.m. JST, Kyodo News reported that a worker spotted new flames on the fourth story of Unit 4, where the spent fuel pool is located. This cast into doubt the earlier hope that the Tuesday blaze in the Unit 4 housing was caused by lubricating oil pumps; instead TEPCO officials acknowledged it was possible the spent fuel rods are uncovered and overheating, remarking that "the possibility of a re-criticality is not zero."[28][29] By midday, NHK TV was reporting white smoke rising from the Fukushima I plant, which officials suggested was likely coming from Reactor 3. Shortly afterwards, reports surfaced that all but a small group[30] of remaining workers at the plant had been placed on standby because of the dangerously rising levels of radioactivity up to 1000 mSv/h.[6][31] Later reports stated that TEPCO had temporarily suspended operations at the facility due to radiation spikes and had pulled all their employees out.[32] A TEPCO press release stated that workers had been withdrawn at 06:00 JST because of abnormal noises coming from one of the reactor pressure suppression chambers.[33] Late in the evening, Reuters reported that water was being poured into reactors 5 and 6.[34]

   * 17 March: During the morning, Self-Defense Force helicopters dropped four containers of water on the spent fuel pools of Units 3 and 4.[35] In the afternoon it was reported that the Unit 4 spent fuel pool is full with water and none of the fuel rods are exposed.[36] Construction work was started to restore power to all six units of Fukushima I.[37]"

Terrible... I hope the Turkish govermnet is doing what it can to help - our Gipsy scum leaders are not doing anything..

Hungarian college students collected some money to help Japan on march 15 - but there is little our civillian population can do...

Szia, Turul Anda ! Nice to see a Hungarian brother in Huntürk. I hope that our Hungarians members will be increased in our forum.

We sent a tiny help to Japan for now.

Turkey sends aid to Japan

Turkey sends aid to Japan

A Turkish team comprised of 33 search and rescue, and technical experts left for Tokyo, Japan on Friday in the wake of the devastating earthquake and tsunami, Anadolu agency reported.

A ceremony was held at Istanbul's Ataturk Airport before the team flew to Tokyo.

Speaking at the ceremony, Japanese Ambassador to Turkey Kiyoshi Araki said the disaster zone was cold and quake victims were waiting for this search and rescue team.

Araki said he believed the team would carry out efficient initiatives there.

Yalcin Mumcu, the director of Bursa Civil Defense Search and Rescue Unit heading the team, said they were carrying radiation measuring devices with them.

"We will do our best, and we are going there to share the agonies of people," Mumcu also said.

Moreover, Turkey will send three vehicles, two trailers, 40 dosimeters, five radiation measuring devices to Japan later on Friday.

According to recent reports, 5,600 people lost their lives and 2,400 others were wounded in the devastating earthquake and tsunami disaster that hit Japan. 9,500 people have been reported missing.

Around 380,000 people have been evacuated from their places so far.

Last week's 9.0 quake and tsunami set off the nuclear problems by knocking out power to cooling systems at the Fukushima Dai-ichi plant on the northeast coast. Since then, four of the troubled plant's six reactor units have seen fires, explosions or partial meltdowns.

The unfolding crises have led to power shortages in Japan, forced factories to close, sent shockwaves through global manufacturing and triggered a plunge in Japanese stock prices.

Tnak you, Türk-Kan anda. I hope so too.

Well - better than the 2 people our government sent for 2 days... But AKP...

If it were up to me I would send at least 3 planes full of people (even a small country could afford that) - and food and clothing.. The Japanese always help everyone else too.
